Noticed while playing “Valley”, which was causing some 8MB of leakage per
second. kmemleak listed many entries looking like this:
unreferenced object 0xffff8802c2951800 (size 1024):
comm "Xorg", pid 2982, jiffies 4297410155 (age 392.787s)
hex dump (first 32 bytes):

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
